This is an area of potentially bewildering complexity. Specialist legal advice is vital as is careful strategic thinking. There is little purpose in obtaining an order which simply is unenforceable.
There are many different international reciprocal enforcement arrangements currently in place. What and where will decide which arrangement applies. In other words, you have to consider the particular type of English court order involved and the country in which you wish to enforce it. A distinction is drawn between maintenance orders (which can in certain circumstances include lump sums and transfers of property) on the one hand and other types of orders on the other. The reciprocal arrangement in Europe for enforcing maintenance is Brussels I.
Consent orders for maintenance are now much more easily enforceable within the EU under the European Enforcement Order.
The English court has the power to make an order against foreign property (for example, a transfer of property order transferring the property from one party to another) although in practice it will only exercise this power if it is satisfied that the order is capable of enforcement abroad.
